I have the window problem that is only moves one inch then stops and then in 5 min you try again and get another inch. I believe this is a motor overheating. I havent opened the door yet but am confident I need a new motor. I found a source for a right door motor and am sure the gearbox is different, but maybe the motor itself is identical. Anyone know If I can just swap out the motor using one from the passenger door, if the gears are OK ???

I would also consider replacing the window run (rubber) and the regulator…if the run is bad it can wear out a new motor more quickly I believe.

It is more likely that it stops because of the safety mechanism that prevents the window from cutting off your fingers.
I would have the door panel off first and lube the channels and mechanism before considering a new motor.

Electric motors don't generally get weak with age. They either work or they don't.

Been there done that. its NOT the tracks. Its the heat and the motor. Probably a motor heat cut off.

I worry that the aged PTC built inside of the motor is causing the problem as is discussed here. I usually just replace the PTC when it's available at Akihabara Tokyo.
